NMR spectroscopy and applications

During the last decade electromagnetic (EM) methods have become an accepted tool to reduce offshore hydrocarbon exploration risk (Constable, 2010). As an alternative to CSEM with moving horizontal sources PetroMarker developed an offshore, time domain EM method based on vertical, stationary transmitters and receivers (Barsukov et al., 2007). In this paper we present a case study for this method over a Norwegian oil prospect. Kakelborg PL 370 lies about 25 kilometers northwest of the Statfjord Nord field in the North Sea and is operated by Wintershall Norge. A vertical-vertical time domain EM survey was conducted over the Kakelborg prospect by PetroMarker in summer of 2009. After processing and inversion of the EM data it was predicted that the prospect is dry. In July 2012 wildcat well 33/6-4 was drilled without discovering hydrocarbons.
